Unsupported platform: ${platform}

Error message

Unsupported platform: ${platform}

What it means

The npm postinstall script maps process.platform/process.arch to a Rust target triple via TARGET_MAP to select a prebuilt openhuman-core archive; an OS not present in the map (only darwin, linux, win32) has no prebuilt artifact, so installation aborts immediately.

Solutions

1. Install on a supported OS (macOS, GNU/Linux, Windows)
2. Otherwise clone the repo and build from source: cargo build --release --bin openhuman-core, then npm install --ignore-scripts and point to your binary
3. File an issue requesting the target triple if you can supply builds for it

const SUPPORTED_PLATFORMS = ['darwin', 'linux', 'win32'];
if (!SUPPORTED_PLATFORMS.includes(process.platform)) {
  console.error(`No prebuilt openhuman-core for ${process.platform}; build from source`);
  process.exit(1);
}

const hasPrebuilt = (p: NodeJS.Platform): p is 'darwin' | 'linux' | 'win32' =>
  p === 'darwin' || p === 'linux' || p === 'win32';

When it happens

Trigger: npm install on an OS outside {darwin, linux, win32}: FreeBSD/OpenBSD jails, Android Termux, Solaris/SmartOS containers.

Common situations: Installing the CLI inside Termux or a BSD sandbox; exotic CI runner images.
